      Laryngotracheal trauma is rare but potentially life-threatening as it implies a high risk of compromising airway patency. A consensus on damage control management for laryngotracheal trauma is presented in this article. ...
    • Carvajal, Javier A.; Ramos, Isabella; Kusanovic, Juan Pedro; Escobar, María F. (Taylor & Francis, 2020)
      Severe obstetric hemorrhage is a catastrophic event and represents the main cause of maternal morbidity and mortality worldwide. The elevated mortality rate due to hemorrhage is associated with metabolic complications and ...
    • Gomberoff, L.; Araneda, J. A. (2001)
      It is shown that damping effects can destabilize regions that are stable under non-dissipative fluid theory. Damping effects on the ion-acoustic modes are simulated by a collisional-like term in the longitudinal component ...
    • Rothhammer Engel, Francisco; Manríquez Soto, Germán Raúl (Sociedad de Biología de Chile, 2001)
      El concepto de coadaptación es antiguo en biología. Darwin (1859) se refiere a la "gran cantidad de complejas e indispensables coadaptaciones estructurales existentes entre un ser orgánico y otro". El concepto también fue ...
